Application filed June 14, 1902. Serial No. 111,718.

To all whom 'it may concern.

Be 1t known that we, lmnmr H. (lmss and W iLLiAM Z. BEAN, citizens ofthe Quincy, county of Norfolk, and West Med ford, county of Middlesex,and State of hlassachusetts, have invented an Improvement inllyeleting-lvlaehines, of which the following description, in connectionwith the accompanying drawings, is a specific-ation, like letters on thedrawings representing This invention has for its object the productionof a novel eyeleting machine by which an eyelet may be taken from araceway and set in stock at each cycle of 0pera. tions of the machine.

ln the machine to be herein described a punch makes a hole in the stockand feeds the latter in position over the ascending plunger and lowerset, the eyelet to be set surrounding the plunger.

Figure 1 in front elevation represents a sufficient portion of aneyeleting machine embodying our improvements in one of the liest formsnow known to us, to enable our invention to he understood; Fig. l is asectional detail showing the shaft N3 and its eccentric n2; Fig. 2 is a`sectional detail in line ad, Fig. 1, showing shaft Agand its eccentricG; Fig. 3 is a right hand side elev,. tion of the machine shown in Fig.1; Fig. it shows the inner side of arm J5 detached: Fig. 5 shows thelower end of lever D2 and the trip device;-I `igs. 6 and 7 show part ofthe shank of the Work clamp and its attached block and dog; Fig. 8showsin section the support for the toggle; Fig. 9 is a shown in Fig. 1partially broken ont; 10 is a partial section in the line ai', Fig. 3;Fig. 11 shows part of the lower end of the raceway; Fig. 12 shows thepunch and upper set partially in section.

The framework A of the machine adapted it a portion A suitably bored toconstitute a bearing for the shaft .A2, and a. guide for the bar Acarrying the under set A* containing a freely movable plunger A?sustained lby a spring A in usual manner.

The frame suitably bored to receive a B the upper face of which, byvabutting tl.

fran'iework, prevents the undue rising of the said rock-shaft, and keepsthe flange B2 of a head B3, secured to said rock shaft "1y a set screwB, seated on the upper end of the framework. l

The lower end of the rock shaft B has secured to it by a suitable setscrew C* or otherwise, a collar'C having a stud C? surrounded by aroller C3. The roc-k shaft B is surrounded by a spring Cl the lower endof which is fixed to the framework, while the upper end thereof enters aboss C5 depend- 'ing from the head B3, said spring acting normally tohold the head in position for the proper action of the bar D carryingthe punch to be described, that the latter when operated may punch thestock.

The 4outer end of the head B3v is bored to vreceive the bar D providedat its lower end with a. combined punch and upper set, said punch andupper set being represented as detachable from lthe bar. Fig. 12 showspart of the bar and the punch and upper set in .section andy enlarged,and in said figure, u

represents the punch, and a the shoulder or surface that acts as theupper set.

The bar D is threaded externally, sce Fig. l), and receives a. nut a2the top of which abuts the lower end of a slotted sleeve 0,3 secured tosaid bar by .a set screw r1.4. The threaded upper end of the barreceives a nut if. represented as having a tubular lower end that entersthe bearing f1. at the end of the head B3. The sleeve a is slotted asshown at its rear side, .and receives a stud D carried by a punch leverD2 having its fulcrum at D3, see Fig. 3, on an arm D* independent of thehead B, said arm forming part ofthe framework. This arm -is shown asfixed to said framework by a bolt Diam-la hole in the end of said armsurrounds loosely a rock shaft DG to bedescribcd.

The lower end of the punch lever D2 is extended downwardly, andA haspivoted upon it at 'b a trip device b', shown partially by dotted linesFig. 3 and detacheth in Fig. 5, said trip device' at its lower endcarrying a stud b2 provided with a roller ha. The upper end bfyof thetrip device ZJ is'niaip tained in its normal or inoperative positionsonia/i in Contact 'with a stud o5 of lever l)2 by af shaft A2 by theoperator causes said cani to spring' o, spring c connected at one endwith the arm D* by a stud c and engaging by its opposite end a stud Zroi" lever D2 acts to turn the lever l)2 in a direction to maintain thepunch and top in their elevated inoperative position. To restrain therotation of the. sleeve fr in the head ll, a stud c2 connected with saidsleeve enters and is free to slide through a suitablel hole in the headB3. By turning the nuts u and a? the bar D may be raised or lowered toattord exactly the proper position for the punch in its descent that itmay cut through the .material sustained on the Work support E.

The eyelets to be used will be deposited in an eyelet box l sustained inusual manner at the upper end of the race'vay E?. The eyelets in the boxnmy be kept properly agitated by means ol a plate having brushes ofusual construction carried by the shaft E having ils bearing in a hub ofthe plate E2, the lower end ol said shalt having attached to it a c ankarn'i lil1 with which is attached a link E5 connected in turn at itsopposite end With an arm E extended from the rock shaft DG.

The eyelets pass'lfroin the hopper E down the usual raceway composed ofbars EX attached to the raceway plate E2 by suitable screws 2, and inpractice there is ay row of eyelets betweenthe lower extremity of theraceWay and the hopper, and the loivei'niost eyelet a* of the row andthose back of it are retained in the raceway by means of a springcontrolled dogl d, see Fig. 11.

The raceway plate has suitable ears 3, 3X, to which are jointed by studscrews or pins Lle 41X, raceway sustaininglmeans represented as radiusbars 5, 5X. The radius bar 5 is mounted on a stud 6, and said bar has aroller or other stud 7,'and a spiral spring 8, represented assurrounding the stud S and acting against the radius bar 5 servesnormally to keep the rller stud pressed toivard a cam to be describedthat in its action moves the raeevvay baclnvardly from the path oimovement of the plunger A5 after said plunger has entered an endinosteyelet of the raceway.

The lower end of the radius bar 5X has a split hub that embraces aneccentric bushing (l which is clamped in said hub by a screw :T3/l, saidbushingA G surr/.iundingl said shaft.

this bushing, shown by dotted lines Fig. 1

and in section Fig., 2 has a series of holes i0. to he engaged by asuitable tool 'when the slacliened, the turning of .sa-id bushi said barinsuring the proper position fo the plunger 'the shaft l? has clampedouter end by a clamp scren7 'tuator firmly upon its Cr a cam or acthatni the movements of the rock lower end of the ra e'ivay With rclathat isto enter tue eye-v Ithereon, and at. the

actagainst the roller C3 of the stud. (l and swing the head B in thedirection ot' the ars row Fig. 1, so that when the punch a is yet in thesteelt, it having punched a hole therein, the head B may be swung tofeed the stock` into proper position above the plunger, as will bedescribed, to enable an eyelet to be set.

The stock into which the eyelets are set will be sustained on a Worksupport E of usual construction secured to the framework by a suitablebolt G.

The stock to be punched preparatory to receiving an eyelet, is' actedupon bya suitable clamping presser foot .H connected by :i set screw Hwith the upper end of a rod l-ll guided in suit-able bearings of theframework. Said f'od is surrounded by a spiral spring H that actsnormally to keep the presser foot down upon thc face of the stock, thelower end of said spring bein sustained by a collar H5 secured tosaidrofl by a suitable clamp screw HGy seeFig. 1. The collar Hf has a stud13, see Figs. 3 and G, upon which is pivoted a dog 14 controlled by a,spring 15, said spring acting normally to keep a projection 16 at theupper end of said dog yieldingly in contact With said collar H5. -Theshaft A2 has clamped upon it at one end by clamp screws il the split.hub J' of a. lever J2 provided at its u )per end with a, suitable studJ3 that is em raced by the bifurcated upper end'of a rod J4 extendeddownwardly and connected with a suitable treadle, not shown, under, thecontrol of the operator, so that When said treadlc is depressed by theoperator the lever J2 will be moved in the direction of` the arrow on itin F ig. 8, a suitable spring, not shown, connected With the treadle andwith the rod near its lower end, actingr normally to maintain in thelever Jin the full line position Fig. 3fr The rock shaft A2 has clampedto it by a screw JX the split hub oi an arm J5, that has jffiiited to itby a suitable stud a link il in turn jointed at its opposite end to anarm JT depending from the rock shaft D, so that the movement of the rockshaft A2 moves the shaft D6 through the devices described. The shaft Dis provided at its opposite end, see Fig. 9, with a main cam K fastouter side ot said cani said shaft is provided with an auxiliary cam orretarding device K which is 'loose on said shaft, said auxiliary caniupon by a spring` l@ represented as interposed betiveen said cams l andl so that said springaT acts normally to keep the auxiliary canili insuch position with relation 'to the roller T that. when the roch shaft Dis turned to cause the cam l( to move he raceway backwardly, the plungerhaving risen'ivithin the cudmost eyelet, Athe retarding device or camlil will first contact vh being acted lli-t device or cam K stro ve theroller D2 is turned c this timethe retarding device' or cani yieldsthereof-in Contact with-roller 7`co1nesinto the roll 7, but the springK2will enable saidvcam to yield so that the arm 5 will not be moved untilthe main cam 'K meets the roller 7 and causes the movement of theraceway backwardly in order that the eyelet on the end of the racewayand .at that. time entered by the plunger may be automatically pickedolf and left on the plunger.

The raceway after the setting operation has been completed and the underset `and plunger have been retracted into their normal inoperativeposition, must resume its operative position to thereby present theendmost eyelet to the risingn plunger at the next cycle of tion of themachine.

By the use of only the cam K, the race way will come back into itsoperative position belore the plunger and under set arrive in theirnormal inoperative position, and would meet the plunger to its injury,hut by the employment of the retarding device or cam it has been foundthat the cam K may -loe started. backwardly from Contact with the rollerstud 7, but the raceway will not be moved forwardly by the spring 8until afterthe spring controlled retarding retires from its contact withthe stud.

The arm J has connected to it at its inner side, see Fig. 4, a cam block18, and said arm also has a roller stud 19.l

Then the arm J2 is depressed as described and the arinJ is moved to theright, Fig. 3, the end 20 of the cam block 1S meets the roller stud b3at the lower end of the trip device 7)', and the upper end thereofbeing` then in contact with the stud "b5, the lever to depress the barcarrying the punch und the upper set, causing thel punch to meet theface of the stock and punch a hole therein.

J st as the punch is completing its down stud`19 meets the end of thedog 14 pivotedon the block H.and act ing on said dog starts upwardly therodI H2 and stock-clamp or presser foot H to relieve the pressure on thestock that it may be fed while the punch is yet in the stock.

In the furthermovement of the arm J5 after releasing the stock clamp,the link J" turns'the rock'shaft D and brings the edge oi' theretardin'g device K( in Contact with the roller stud 7, and the inclinedface 240 ofu downwardly projecting arm M connected with the rock shaftA2 meets the jointed part of--a toggle leverhl M1, and .st-arts upwardlythe-bar carrying the undersetlaud plunger.A This pllmger enters theendinost Veyeletfon -the'raceway, and duringVA nndertlie.'action-.of itsspring,l until the edge alinementwith. the 4rear `edge of the main nainK. Inthemeautiine the roller stud `Z13 has arrvedupon and passed overthe proavai-diy the lower set jection 25 of the cam 18, which permitsthe spring o -to act and turn the lever D2 stifliciently to Withdraw thelower end of the punch from Contact with the stock support,

but leaving the punch in the stock. As-

the stock but lifted from contact with the stock support, so that thepunch may feed the stock over the stock support and place the punchedhole in line with the plunger, and at the same instant the cani K actsto move the raceway away from the plunger.

As the plunger and lower set rise, the plunger surrounded by the eyeletenters First the hole in the hole in the end of the punch, and while theplunger is arrested in its upward position the under set rises, forcesthe eyelet off the plunger through the hole in the stock, the eyeletpasses over the outside of the punch, and the small end of the eyeletmeets Ythe shoulder a constituting the upper set,'and the final upwardmovement of the under set sets the yelet in the stock.

Just about as the setting operation is comT pleted' the roller stu'd b3leaves entirely the cani 18, Athus letting thev spring c act quickly tofully withdraw thepunch `from the stock and return thepunch into itsnormal inoperative position, and at the saine time the roller stud 19passes beyond the dog 14, letting the spring H4 depress the stock clampor presser foot ontothe stock.

`VVhen lthe arm J 2 has been fully depressed by the operator, the punch.vill have rcturned to' its inoperative position, the stock clamporpresser foot will clamp the stock on the stock support, and theplunger and under set will occupy their highest positions, and an eyeletWill have been set. f

As the arm J2 is raised from' its depressed punched stock, and then theposition after the operator removes his foot from the treadle referredto, the rock shaft D and cam K are started backwardly, and the rockshaft AL is turned, causing the arm M to retire from the toggle joint,enabling the spring N surrounding the'fulcrum sustaining the lowerm'ostlink M of the toggle to act and break the toggle and start downthe lowerset is arrivingr in its lowermost position the cam K, 1f acting alone,Would let the racewa-y move forwardly under the `action of spring 8, butowing to the reta` da'uxi'hary cam Ythat acts ing device or the main camK retires-from the roller stud 7', the forward movement ofv the racewayis"- retarded untilsuch time as the bottom set and plunger lia-ve4arrived in their eXtreme lowermost position, so that the end of` theandplunger. About as p raceway isprevented from strikingt-hebottoni 'setort-he plunger, and-injuring the" ,sa me.

` represented in Fig. 3. At

v lower During the rising movement of the arm J2 the cam G5 is alsoraised so that just as the raceway comes forward into its operaT tiveposition, the spring C4 surrounding the shaft B acts to return the headB3 and the b without at all affecting the movement of the lever D2, andfinally the end 20 of said cam passes" said roller stud, permitting thespring b coacting with said trip device to turn said device into itsoperative position the same time the 'roller stud 19 carried by the armJ 5 passes the doO 14 with-out at all affecting the position o thepresser foot, andsaid stud stops in a position represented in'Fig. 3,ready to again meet the dogfll and lift the presser foot whenever thearm J2 is depressed.

The work-support may be provided with a suitable gage of ordinary formWhich forms no part of the present invention and hence is unnecessary toillustrate.

The lower arm M of the toggle, see Fig. 8, embraces an eccentric N2suitably keyed or secured to the stud N3 held in depending ears N4 ofthe framework by a suitable set screw N5. One end ofthe stud N3 issuitablv shaped to may be turned ,to adjust the eccentric and therebyraise or lowerthe support for the member of the toggle. This adjustmentenables the upward movement of the under, set and of the plungersustained thereby to be exactly regulated so that said a hole in plungerand under set may coact properly with the punch and upper set.

From the foregoing it will be seenI that the operator by one movement ofthe-treadle, a manually 'controlled device, is enabled to clamp thestock on .the stock support, punch p the clamped stock, Vrelease theclamped stock, feed the same, move a plunger to enter an eyelet at theend of a raceway, move the nraceivay to detach the eyelet and leave iton the plunger, and then further move the under set to force the eyeletfrom the plunger into the stock, and set the eyelet by upsetting thesaine in the stock, the parts actuated to do these things being ther 1.areturned automatically' into their starting position.

Tfc also believetliat we are the first to inove 'a i'aeeway backwardlyby means that act together when moving theraceway away from the plunger,and that :ict in succession, o r one after the other, or
